Achieving excellence in anterior rehabilitations requires close cooperation between the periodontist and the prosthodontist. Many techniques can be used to restore the lost alveolar hard and soft tissues. The more severe the peri-implant defect, the higher the challenge and lower the predictability of the procedure. The present case consists of Seibert class III with mal-aligned implants in the esthetic zone resolved with a cost-modified treatment plan to re-establish esthetics in the anterior maxilla using rotated palatal flap...

The success of osseointegration is influenced by several factors that affect bone metabolism and by certain systemic medications. Selective serotonin reuptake inhibitors have been previously suggested to be among these medications. This study aims to investigate the association between systemic intake of SSRIs and failure of osseointegration in patients rehabilitated with dental implants. A retrospective cohort study was conducted including a total of 2055 osseointegrated dental implants in 631 patients (109 implants in 36 SSRI-users and 1946 in 595 non-users)...

This technique describes a novel approach for planning and augmenting a large bony defect using a titanium mesh (TiMe). A 3-dimensional (3D) surgical model was virtually created from a cone beam computed tomography (CBCT) and wax-pattern of the final prosthetic outcome. The required bone volume (horizontally and vertically) was digitally augmented and then 3D printed to create a bone model. The 3D model was then used to contour the TiMe in accordance with the digital augmentation. With the contoured / preformed TiMe on the 3D printed model a positioning jig was made to aid the placement of the TiMe as planned during surgery...

Current challenges in the field of regenerative medicine include the need to deliver sustained concentrations of growth factors and genes that are required to induce the repair of deficient tissues. Enhancement of drug delivery and uptake may result in improved growth factor efficacy. Nanodiamonds (NDs) were explored as potential growth factor delivery agents due to the many favorable properties that they possess. For example, ND's biocompatibility has been extensively validated pre-clinically. In addition, they can be scalably produced through impact events such as detonation...

Aim of the study was to evaluate the reliability of 6 mm long implants compared to normal length implants placed in vertical augmented atrophic posterior mandible, supporting cemented single crowns. Thirty-six patients with bilateral posterior edentulous mandible and presented a bone availability height less than 9 mm from the mandibular canal were enrolled for the participation to this study. Patient hemi-arches were randomized to receive both 6 mm-long and normal length implants (10 mm). The technique used for the vertical bone augmentation was the "sandwich" technique, using a bone substitute block as graft...

Florid cemento-osseus dysplasia (FCOD) has been described as a reactive process in which normal bone is replaced by fibrous connective tissues and cementum-like materials. Radiographically it appears as dense, lobulated masses, often occurring bilaterally with symmetric involvement. In this case report a successful implant placement has been reported in a 62-year-old Caucasian woman with a chief complaint of mandibular partial edentulous. Radiographic images showed the bilateral radio-opaque lesions in edentulous regions of mandible, and mandibular anterior teeth alike...

The fear of postoperative pain is often mentioned by patients as one of the factors that is most frequently associated with dental implants. In an attempt to reduce this factor, a single oral dose of 25 mg dexketoprofen trometamol (DKT) or PLACEBO was administered 15 minutes before implant surgery. One hundred patients who required single-implant treatments were randomly assigned to one of two blinded groups. The patients in the test group were given 25 mg of DKT (DKT group), and those in the control group were given 500 mg of vitamin C as a placebo (PLACEBO group)...

Reconstruction of bone loss in the alveolar ridge has long been challenging. Autologous bone grafts are considered as the "golden standard", while little research has focused on how to repair pronounced alveolar bone defects after autologous bone graft failure. The aim of this study was to detail a method based on the titanium mesh technique coupled with particulate coral hydroxyapatite to solve the Onlay graft failure. With bone deficiency in the #11 and #24- #25 regions, we harvested two autologous bone blocks for reconstruction...

The success of implant-based treatment is dependent on the correct restorative position of dental implants in the oral cavity. Often, the final prostheses require dental implants to be placed at sites with inadequate native hard and soft tissue. Bone augmentation procedures and materials have been extensively studied in the literature and various techniques have been developed over time to obtain adequate hard tissue at proposed implant sites. In the recent past, few publications have also studied soft tissue development at planned implant sites...

This study evaluated the outcomes of CAD-CAM customized titanium mesh used for prosthetically guided bone augmentation related to the occlusion driven implant position; to the vertical bone volume gain of mandible and maxilla; and to complications, like mesh exposure.. Nine patients scheduled for bone augmentation of atrophic sites were treated with custom titanium mesh and particulate bone grafts with autologous bone and anorganic bovine bone in a 1:1 ratio prior to implant surgery. The bone volume needed to augment was virtually projected based on implants position, width and length, and the mesh design was programmed for the necessary retaining screws...

To achieve re-osseointegration on implant surfaces exposed to peri-implant infections, treatment should re-establish biocompatibility. The aim of this study was to test whether air powder abrasive treatment (APA) using osteoconductive powders can, in addition to cleaning, increase the biocompatibility of the contaminated implant surface. 96 in-vitro Ca-precipitated, organic-film-layer-coated SLA titanium discs were treated by APA using Erythritol, Hydroxylapatite (HA) and Biocalcium Phosphate (BioCaP) powders (n=16 per group)...
